# pam_radius_auth configuration file. Copy to: /etc/raddb/server
#
# For proper security, this file SHOULD have permissions 0600,
# that is readable by root, and NO ONE else. If anyone other than
# root can read this file, then they can spoof responses from the server!
#
# There are 5 fields per line in this file. There may be multiple
# lines. Blank lines or lines beginning with '#' are treated as
# comments, and are ignored. The fields are:
#
# server[:port] secret [timeout [source_ip [vrf]]]
#
# the port name or number is optional. The default port name is
# "radius", and is looked up from /etc/services The timeout field is
# optional. The default timeout is 3 seconds.
# The source_ip field is optional and the default is none.
# The vrf field is optional and the default is none.
#
# For IPv6 literal addresses, the address has to be surrounded by
# square brackets as usual. E.g. [2001:0db8:85a3::4].
#
# If multiple RADIUS server lines exist, they are tried in order. The
# first server to return success or failure causes the module to return
# success or failure. Only if a server fails to response is it skipped,
# and the next server in turn is used.
#
# The timeout field controls how many seconds the module waits before
# deciding that the server has failed to respond. Timeouts MUST be
# between 3 and 60 seconds. If they are outside of this range, the
# timeouts are clamped to this range.
#
# The source_ip field can be used to make the library bind the socket
# that connects to that particular server to a particular IP address.
# Note: specifying a timeout field is mandatory due to config parsing,
# but if not needed it can be just set to the default of 3.
#
# The vrf field can be used on Linux to make the library bind the socket
# that connects to that particualar server to a particular VRF.
# See: https://www.kernel.org/doc/Documentation/networking/vrf.txt for
# more information.
# Note: specifying a source_ip field is mandatory due to config parsing,
# but if not needed it can be just set to 0.
